NV D32 Shipbuilding steel plate
NV D32 steel for shipbuilding is not only the high tensile strength steel but also is the Hull structural steel with good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and good welding properties.Shipbuilding steel grade NV D32 steel is used for shipbuilding and oil platform purpose and they are approved by ABS,DNV,GL,BV,LR,NK,RINA and other classification societies.What's more, NVD32 shipbuilding steel plate can be used in manufacturing the ship's hull structure whose weight is below 10000 tons.
